Why you SHOULD NOT leave your campervan plugged into your home all the time!

We’re going to get a little nerdy here, but for good reason.

Many campervan and motorhome owners tend to leave their campervans and motorhomes plugged into their houses whenever they’re not using it. Why? Well it keeps the batteries topped up via a battery charger and even offers the option of running a space heater to mitigate dampness and condensation.

Electrons

Why leaving your campervan plugged into a household electrical system could be dangerous

Leaving a campervan plugged into your house’s electrical system can pose serious safety risks, particularly if there are issues with the property’s electrical installation.

One significant concern is the potential loss of the Protective Earth and Neutral (PEN) conductor on the incoming supply, which can lead to detrimental effects and create a hazardous situation.

Loss of PEN Conductor:
The PEN conductor in a TNCS, TNC or TN-S supply, serves as both the Protective Earth (PE) and Neutral (N) connection within one single core. If this conductor is lost, the normal return path for current is compromised.

The loss of the PEN conductor can result in an unbalanced electrical system, with potential differences between the neutral and ground. This can lead to dangerous voltages on exposed metal surfaces within the campervan.

Electrons

Potential for the Van to Become Live:
With the loss of the PEN conductor, the chassis of the campervan, which is typically connected to the Protective Earth, may no longer be at the same potential as the neutral conductor.

If a fault occurs within the campervan’s electrical system and the chassis becomes energised, there is a risk that the entire campervan could become live with electric potential. This poses a severe shock hazard to anyone coming into contact with the campervan or its surroundings.

Electric Shock Hazard:
If a person touches the campervan while standing on the ground or any other conductive surface, they may complete an unintended electrical circuit. This can result in electric shock, which can be potentially fatal.

Fire Hazard:
The loss of the PEN conductor may lead to increased resistance and heating in electrical components. This elevated heat can pose a fire hazard, especially if the campervan’s wiring is not designed to handle such conditions.

Damage to Electrical Appliances:
Unbalanced voltages can also damage sensitive electrical appliances and equipment within the campervan, leading to malfunctions and potential safety hazards.

Now you’re probably thinking, this sounds a little far fetched but the truth is, you’re essentially plugging a vehicle into a residential electrical system in order to charge it, exactly the same as an Electric Vehicle (EV) car charging station.

The regulations surrounding EV chargers are incredibly strict, actually so strict its a separate qualification altogether for us electricians. Installations require their own earthing arrangement or PEN fault protection depending upon the installation as well as their own Residual Current Device (RCD) in place to mitigate any risk of electric shock to anyone who comes into contact with the vehicle.

Home car charging point

If you’re sure your house isn’t on the three earthing arrangements mentioned above, then you’re safe.

Typically, properties in more rural locations are only supplied with Line and Neutral conductors and its up to the electrician to provide an earth, commonly via a copper rod or copper tape.

Conclusion

Winterising campervan electrics is a vital task for any enthusiast looking to protect their investment and ensure a trouble-free travel experience.

While safeguarding against the elements is crucial, paying attention to the electrical system is equally important. By plugging your campervan into shore power and starting the engine regularly, you can preserve the functionality of your electrical components and extend the life of your batteries. Don’t let winter catch you off guard – take the necessary steps to winterise your campervan and enjoy worry-free adventures when the warmer months return.

Campervan Electrical Basics Explained

Electricity is a fundamental force that powers our camper vans electrical system. It’s the energy behind our cold beers in the fridge, movie nights with friends and that long shot shower after a day in the surf. Yet, for many, the world of electricity remains a mystery.

In this article, we will break down the basics of electricity, introducing concepts that will help you understand your van conversions electrical layout and system.

Be rest assured, if understanding the fundamentals isn’t for you, we at Tiny Build Electrics take all the confusion of electrical out of the equation and create you your very own wiring diagram (schematic) specific to you and your van build as well as guiding you step by step through the installation process.

Simplified Terminology & Definitions

DC – Direct Current is electrical current that flows consistently in one direction. Commonly used in batteries.

AC – Alternating Current is an electrical current that switches back and forth at regular cycles. Commonly used by the grid.

230V AC – Voltage size and type in the UK and Europe’s Electrical Network.

12V DC – A extra low voltage power supply.

Inverter – A electronic device that converts Direct current (DC) into a Alternating current (AC).

Battery – A container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.

Resistance and Ohm’s Law

Now, before I lose you and you click away because this brings back harrowing memories of GCSE physics, let me reassure you that if there was one algebraic equation worth noting for your campervan electrical build, its this one. It’s a key fundamental that will help you tremendously with your build.

Let’s introduce the concept of resistance, denoted as “R.” Resistance opposes the flow of electrons in a circuit. It’s like a narrow section in a water pipe that restricts the flow of water. Resistance is measured in ohms (Ω).

Ohm’s Law, formulated by Georg Simon Ohm, relates voltage, current, and resistance in a simple equation:

V = I x R

Where:
V represents voltage in volts (V).
I represents current in amperes (A).
R represents resistance in ohms (Ω).

This equation shows that voltage is directly proportional to current and resistance. In simpler terms, it means that increasing voltage will increase the current in a circuit if resistance remains constant. Conversely, if resistance increases, current decreases for a constant voltage.

Ohm Amp and Volt

Using Ohm’s Law in your campervan electrical system

So you want to work out what size cable, fuse and isolator you require for your shiny new fridge in your campervan.

You check the fridge’s manufactures instructions and the maximum power usage is 60 watts.

The campervan’s system voltage is 12 volts.

Now, we can input these numbers into the aforementioned equation.

60 watts divided by 12 volts = 5 amps

Therefore you require a cable capable of carrying 5 amps, a fuse capable of protecting said cable and an isolator able to withstand a minimum of 5 amps will power your fridge safely.

  • 1.5mm 2 core cable with a current carrying capacity of 21 amps. (A short run of cable in conduit assumed)
  • 10 amp fuse capable of protecting the cable (less than 21 amps) but also supplying the 5 amps to the fridge.
  • 10 amp isolator capable of making and breaking the 5 amp current without incurring any damage.

*Note – A fuse is used solely to protect the cable and ensure it does not overheat or cause any damage. The fuse size should always be less than the current carrying capacity of the cable.

Camper Van

Current Carrying Capacity of a Cable

The current carrying capacity of a cable refers to its ability to safely conduct electrical current without overheating or causing damage. This capacity is influenced by various factors, with one of the most significant being the installation method of the cable. When a cable is installed, it is often surrounded by different materials, such as insulation, conduit, or even air. The installation method affects the cable’s ability to dissipate heat generated during the flow of current.

For instance, cables installed in open air typically have a higher current carrying capacity because air provides better heat dissipation compared to enclosed spaces. In contrast, when cables are installed within conduit or buried underground, their current carrying capacity may decrease due to the reduced ability to dissipate heat. Additionally, factors like ambient temperature, cable size, and conductor material also play a role in determining the current carrying capacity of a cable. Therefore, selecting the appropriate installation method is crucial to ensure the cable can safely handle the intended electrical load.

Inverter

Current Flow in a Circuit

Now that we’ve got through the algebra, let’s understand how electrons flow through a load, which is any device in a circuit that consumes electrical energy, like a light, fridge or a fan.

Voltage Source: Every circuit begins with a voltage source, such as a battery or an electrical outlet. The voltage source provides the potential difference that pushes electrons through the circuit.

Batteries

Conductor: Wires made of materials with low resistance (usually copper) connect the voltage source to the load. Electrons flow through these conductors from the negative terminal (where they are pushed away) to the positive terminal (where they are attracted).

Conductor

Load: The load is the part of the circuit that consumes electrical energy. When electrons pass through it, they work, such as producing light or generating heat in the case of a light bulb or a heater.

Campervan lights

Return Path: Electrons don’t disappear after passing through the load. They return to the voltage source via the negative or neutral wire, completing the circuit.

Positive and Negative

How does an inverter work in a campervans electrical system?

An inverter in a campervan’s electrical system simply functions as a converter. It takes the direct current (DC) from the leisure batteries and transforms it into alternating current (AC) power, which is what most of our household devices require. This is vital because many appliances like laptops, chargers, and kitchen gadgets require AC power to operate. The inverter acts as a bridge, enabling you to enjoy the comforts of home on the road, turning your campervan into a tiny home on wheels, allowing you to use all your devices you would normally use at home.

Understanding Electrons

At the heart of electricity is the electron. Electrons are tiny, negatively charged particles that orbit the nucleus of an atom. In most materials, the outermost electrons are loosely bound to their atoms and can move freely. It’s this movement of electrons that creates an electric current.

Electric Current

Electric current is the flow of electrons through a conductor, such as a wire. Think of it as the flow of water through a pipe. The rate at which electrons flow is measured in amperes (A), commonly referred to as “amps.” Current is the quantity of electrons passing through a point in a circuit per unit of time.

Electrons

Voltage

Voltage, often denoted as “V,” is the electric potential difference between two points in a circuit. It’s what causes electrons to move. Imagine voltage as the force that pushes electrons through the wire, similar to how gravity pulls water down a hill. The unit of measurement for voltage is the volt (V).

Voltage

Understanding the basics of electricity, Ohm’s Law, and the flow of electrons through a circuit is crucial for grasping the fundamentals of electrical systems.

Just like learning to swim, starting with the basics is essential. With this knowledge, you can explore more complex electrical concepts and even troubleshoot simple electrical problems in your campervan. So, the next time you turn on a light switch, plug in your phone charger or turn on your inverter, remember that it’s the movement of electrons and the principles of Ohm’s Law that make it all possible

Simply put, these systems run on a 12-volt direct current (DC) and they’re used to power things like lights, fans, and other smaller appliances. They’re also handy for charging batteries, which can then be used to power other devices.

One of the best things about these systems is how simple and easy they are to use. They’re usually a more affordable option and require less maintenance compared to the 230V systems.

However, it’s important to remember that they have some limitations when it comes to powering larger appliances like air conditioners or microwaves.

Keep in mind that the 12V system relies on the campervan’s auxiliary battery for power, which means you need to keep an eye on the battery’s charge and make sure it gets charged up regularly. Otherwise, you might find yourself without power!

230V AC Systems in Campervans

In campervans, 230V AC systems supply power to larger domestic appliances and devices that require more energy than 12V systems can deliver. These appliances include microwaves, air conditioners, and other home-like conveniences.

To get power for these systems, campervans traditionally rely on an external hookup or ‘shore power’. In more recent years, however, onboard inverters have become the norm. These handy devices transform the typically 12V DC power from the campervan’s battery to 230V AC power, which can then be used to power appliances.

Inverters come in various sizes and capabilities, so it’s important to choose one that matches the power requirements of your appliances. But don’t worry, if you’re not sure, we can help size your system for you.

One of the main benefits of 230V AC systems in campervans is their ability to provide more power, making it possible to run larger appliances. They also allow you to use the same appliances you have at home, which can make your campervan feel more comfortable. However, these systems tend to be more expensive and complex to install and use. Additionally, the necessary components and battery storage can add extra weight to your vehicle, which can affect its overall weight distribution and fuel economy.

12V or 230V Systems in Campervans?

When it comes to choosing the best power system for your campervan, you need to think about what kind of stuff you want to power up. If you just need to keep the lights on and charge your gadgets, then the 12V system will do the trick. But, if you’re planning to bring along big-ticket items like a microwave or air conditioner, you’ll need to step it up to a 230V AC system.

It’s also important to think about how long you’re planning to be out on the road and how much juice you need to keep your devices powered up. If you’re planning a short trip and just need to charge your phone, then a 12V system is probably more than enough. But if you’re planning on living off the grid for an extended period of time, you’ll need to make sure you have enough power to sustain your needs.

Of course, you also need to think about the cost and upkeep of each system. A 12V system is generally more affordable and requires less maintenance, but a 230V AC system will give you more power to play with. Ultimately, you need to choose a system that fits your budget and technical abilities, and that will meet your power needs on the road.

Having Both 12v and 230v Systems in Your Campervan

Having both 12V and 230V systems in your campervan can offer the best of both worlds, as it allows you to power both small and large appliances. This is achieved by using a combination of a 12V DC system for low-power items and a 230V AC system for larger appliances e.g. the blender you can’t live without.

One common setup is to use an inverter to convert the 12V DC power from the auxiliary battery to 230V AC power for larger appliances. This can provide more flexibility in your power supply while keeping costs and complexity to a minimum.

Overall, the decision to have both systems in your campervan comes down to personal preference and your individual power needs. It’s always recommended to consult with a professional (cough, that’s us) to ensure that your system is properly sized and installed to meet your specific requirements.

Conclusion

In conclusion, understanding the difference between 12V DC and 230V AC systems in campervans is essential for ensuring your vehicle is properly powered and equipped for your adventures.

12V DC systems are typically simpler, more affordable, and easier to use, but have limited power capabilities. On the other hand, 230V AC systems can provide more power, but are generally more expensive, complex and require more maintenance. By considering your specific needs and the types of appliances and devices you plan to use, you can make an informed decision about which electrical system is right for your campervan.

Remember, a well-informed decision is the key to a successful and enjoyable campervan experience. Take the time to understand your needs, weigh the pros and cons, and make a decision that will serve you best. Happy travels!
